The MSD Power Grid Controller is designed for the MSD Pro Mag 44 in drag racing applications such as Top Alcohol Dragster, where electronic ignition timing control is allowed with a single or dual Pro Mag system. It provides time-based ignition timing control with dual outputs, along with individual cylinder timing and a pedal retard function with an inhibit delay. An auto pickup signal selector lets it switch to the magneto's internal pickup if a crank trigger pickup fails. Built-in data acquisition records each pass for timing analysis. MSD recommends triggering the controller with a crank trigger system using MSD non-magnetic pickups for the most accurate timing. Programming is done from a laptop over cable or Bluetooth using MSDView software, which builds timing curves with up to 30 points in 0.1 degree increments down to 0.01 second intervals and stores up to 12 curves. Note that ignition timing is retarded 5 degrees when the A/Fuel Controller is installed and must be reset to the engine's specifications.
This part is legal for sale and use on Racing Use Only Vehicles, competition vehicles that are not registered and never operated on the street. It is against the law to install this part on an Emissions Controlled Vehicle (1966-and-newer California-certified or 1968-and-newer federally certified vehicles).

FAQ
What is the MSD 8772 Power Grid Controller used for?
It controls ignition timing for the MSD Pro Mag 44 in drag racing, such as Top Alcohol Dragster classes that allow electronic timing control.
Can it control timing on individual cylinders?
Yes. It offers individual cylinder timing along with a time-based timing curve.
How is it programmed?
It is programmed from a laptop over cable or Bluetooth using MSDView software, with up to 30 timing points and up to 12 stored curves.
Does installing it change base timing?
Yes. Ignition timing is retarded 5 degrees when the controller is installed and must be reset to the engine's specifications.
